ALTERA NIOS CYCLONE III EDITION DRIVER
An error is latched if any characters are received out of sequence or are simply missing. Building and executing the demo application Altera Nios Cyclone III Edition main. Delete the line it provides instructions on setting up the directory structure for those using the project without first reading these instructions.
Nios II Embedded Evaluation Kit, Cyclone III Edition, appselector Hardware Design HAL
Connect the target hardware to the host computer using a programming and debug interface - an Altera USB Blaster is suitable for this purpose. To build the project, simply select 'Build All' from the 'Project' menu. The application should build with no errors or warnings assuming the error statement has been removed and CreateProjectDirectoryStructure.
The initial build will take some time as it generates the entire system library. A launch configuration needs to be created before a debug session can be started.
This only Altera Nios Cyclone III Edition to be done once, after it has been created debug sessions can be started simply by clicking the 'Debug' speed button. In the dialog box that opens, double click where it says 'Nios II hardware' to create a new configuration. The configuration parameters will be set automatically. Finally click 'Debug' to program the MCU and start a debug session. Once the. This is only necessary the first time after the FPGA has been powered up. Setting up the launch configuration Functionality The demo application creates 43 tasks prior to starting the RTOS scheduler.
These tasks consist mainly of the standard demo application tasks see the demo application section for details of the individual tasks. The following tasks and tests are created in addition to the standard demo tasks: Check task This Altera Nios Cyclone III Edition executes every five seconds. Its main function is to check that all the standard demo tasks are still operational. The Check task will toggle LED 7 every 5 seconds provided all the tasks in the system are executing without error.

The toggle rate increasing to ms is indicative of an error being reported in at least one task - the name of the offending task will be written to the Nios II IDE Altera Nios Cyclone III Edition. This mechanism can be tested by removing the loop back connector from the UART and in so doing deliberately introducing an error. Reg Test tasks The reg test tasks fill the Nios II registers with known values before checking each register contains the value expected. A register containing an unexpected value is indicative of an error in the context switch mechanism.

Two reg test tasks are created, with Altera Nios Cyclone III Edition using a different set of register values. If your NEEK board runs a different version of the hardware design then it will be necessary to update the board before eCos can be used. Instructions on how to do this are given below. The hardware design includes the following functionality: This has 4K of instruction cache and 2K of data cache. It has level 1 jtag support only with no hardware breakpoints. The reset vector is at address 0x in external flash and the exception vector is at address 0x in external SRAM. Some of this will be used for exception and interrupt handling.
The remainder is available for use by the application. Code and data can be placed here by putting it into.
